Abstract
Abstract The bars (10) forming the caps are arranged along the whole periphery and are applied to the flanks (12) by screw means (30, 42) for the adjustment of the inclination of the surfaces provided with clothing, in respect to the tangent to the rotating drum (1) of the card in the application zone; yieldings of the bar (10), in a substantially radial direction, are allowed by the intervention of elastic means (34). The lower bars make up a carding grid.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
57 words
A card with fixed caps, characterized in that it comprises -for the formation of caps -bars or rods carrying the clothings which are disposed along the whole periphery of the drum and are applied to the flanks by the intervention of elastic means which allow yieldings of the rod or bar in a substantially radial centrifugal direction.
Claim 2
Dependent Claim
57 words
A card with fixed caps, characterized in that it comprises -for the formation of caps -bars or rods carrying the clothings which are disposed along the whole periphery of the drum and are applied to the flanks by the intervention of elastic means which allow yieldings of the rod or bar in a substantially radial centrifugal direction.
Claim 3
Dependent Claim
36 words
Card according to claim 1, characterized in that it comprises also adjustment means for the inclinafion, of the clothing surfaces in respect to the tangent to the rotating drum of the card in the application zone.
Claim 4
Dependent Claim
62 words
Card according to claim 1 or 2, characterized in that each rod or bar for the formation of a cap has towards each end, guide means for the possibility of a more or less radial centrifugal displacement, and elastic means which urge the bar in the centripetal direction, that is, towards the bearing surface, with a suitable elastic force being also adjustable.
Claim 5
Dependent Claim
44 words
Card according to claim 2 or 3, characterized in that it comprises, towards each end at a position offset of the center line, a screw dowel making up an adjustable pawl for changing the inclination with which the bar rests on the flank profile.
Claim 6
Dependent Claim
30 words
Card according to the preceding claims, characterized in that it comprises more or less radial columns providing guide means for the elastic yielding of the bars in the centrifugal direction.
Claim 7
Dependent Claim
39 words
Card according to the preceding claims, characterized in that the elastic means consist of helicaf, volute or similar springs which act along the columns axis and can be disposed around the columns being suitably provided with a reaction head.
Claim 8
Dependent Claim
33 words
Card according to claim 6, characterized in that it comprises screw adjustment means of the reaction head and/or means for the insertion of shims to be interposed between the bar and the spring.
Claim 9
Dependent Claim
48 words
Card according to claims 1 to 5, characterized in that the elastic means are realized in the form of pneumatic springs so that to obtain the possibility of a simultaneous adjustment of all elastic means of all the bars surrounding the drum or of single groups of bars.
Claim 10
Dependent Claim
36 words
Card according to the preceding claimscharacterized in that it comprises at each end at least two dowels in order to obtain the adjustment of the radial displacement of the bar in addition to the inclination adjustment
Claim 11
Dependent Claim
79 words
Card according to the preceding claims, characterized in that the bar for caps comprises: a beam able to engage, by means of dovetail profiles or other equivalent way, a plurality of side-by-side packed plates forming the clothing; and two end supports, which are fixed at the end of the beam for damping the plates and are provided with the inclination adjustment means and with the elastic yielding application means; said end supports being possibly realized in a right-angle form.
Claim 12
Dependent Claim
29 words
Card according to claim 1 or the following claims, characterized in that it comprises a suction hood sucking from the spaces between the bars of a group of bars.
Claim 13
Dependent Claim
22 words
Card with fixed caps with elastic yielding and inclination adjustment; all as above described and represented for exemplification in the attached drawing.
Claim 14
Dependent Claim
22 words
Card with fixed caps with elastic yielding and inclination adjustment; all as above described and represented for exemplification in the attached drawing.
